Consider an air-standard Diesel cycle. Operating data at principal states in the cycle are given in the table below. The states are numbered as in the figure below. State T(K) p (kPa) u (kJ/kg) h (kJ/kg) 1 380 100 271.5 380.6 2 1096 5194 841.9 1157 3 1728 5194 1417 1913 4 779.8 205.2 575.7 799.5 p=c Determine: (a) the cutoff ratio. (b) the heat addition per unit mass, in kJ/kg. (c) the net work per unit mass, in kJ/kg. (d) the percent thermal efficiency.
